\fBsslproxy.conf\fR \- Configuration file for SSLproxy
.SH "DESCRIPTION"
.LP 
The file sslproxy.conf configures SSLproxy, sslproxy(1).
.SH "FILE FORMAT"
The file consists of comments and options with arguments. Each line which

.SH "DIRECTIVES"
.LP 
When an option is not used (hashed or doesn't exist in the configuration file) 
sslproxy takes a default action. If an option does not have a command line 
equivalent, -o opt=val option can be used to override it on the command line.
